Hello,
I cannot ping the switch nor reach an ip destination from within it. My switch is on v3.4.0.17. pfSense manages my firewall and DHCP server. My default gateway is 172.25.1.1. I have 3 VLANs 10, 20, 30 - subnets 172.25.10.1, 172.25.20.1, etc.
My network had undergone a MiTM attack. And I cannot determine how long the attacker had access to my network. So, among other things, I factory reset my switch and included IP DHCP snooping and ARP inspection in my new configuration. Both of which were critical in getting the attacker to back down - though I'm not certain the attacker is completely out, occasionally an ARP packet drop notice will appear with the public address of 169.254.243.120. But this is also the point when the switch lost its connectivity. I appreciate your help in resolving my connection issue.
